PubPeer, an overseas academic counterfeiting website, recently revealed that Zhan, executive vice president of Peking University, director of Peking University Medical Department and academician of China Academy of Engineering, was suspected of "counterfeiting" his papers. Among the 25 papers questioned by Zhan, they can be roughly divided into three categories: repeated experimental images, violation of animal experimental ethics, common sense errors in experimental results, and ineffective or missing individual primers.

Among these 25 papers, there are two articles that are accused of violating animal experimental ethics, and Zhan's team has not yet responded. Both articles were published during Zhan's tenure as vice president of China Academy of Medical Sciences and vice president of Peking Union Medical College. One of the articles was published in Journal of Clinical Research 20 10 sponsored by American Association for Clinical Research.

On PubPeer, a message posted images of six experimental mice in the paper and asked if the author could clarify the tumor size obtained in this study. Do these conform to the animal ethics of your organization? Zhan is our reporter.

These 25 papers were published in 1998 to 20 19, and ran through the period when Zhan was a senior research assistant at the National Cancer Institute of the National Institutes of Health and executive vice president of Peking University. The papers were published in Natural Communication, Journal of Genetics and Genomics, Cell Death and Disease, Clinical Cancer Research and other journals, and the impact factors of most journals were within 10. Among the questioners, except one of them is Bi Ke, a well-known counterfeiter, the other 24 articles were mainly written by two anonymous accounts.

Extended data

Chen Dong, academician of Chinese Academy of Sciences and president of Tsinghua University Medical College, was also questioned:

Since May this year, anonymous posts have been posted on PubPeer's website, questioning that 24 papers signed by Chen Dong, an academician of China Academy of Sciences and dean of Tsinghua University Medical College, have problems such as multi-purpose and repeated use of one picture.

In this regard, Chen Dong replied to China Newsweek that he reviewed his 20 papers as a correspondent with 10 former doctors and postdocs around the world, and answered every question on the Pubpeer website in detail within one week. Chen Dong emphasized that it can be clearly seen from their investigation and answers that these papers are not fraudulent and there is no academic misconduct.

In response to a questioned paper, Chen Dong said, "We welcome constructive criticism aimed at improving the quality and rigor of science.

However, these problems show a lack of understanding of fields, themes and generally accepted principles in the industry, so most criticisms are of no scientific value. As a loyal supporter of PubPeer Forum, we don't want PubPeer, a professional scientific exchange platform, to be used by some anonymous skeptics to distract scientists from their daily scientific research activities, which will run counter to the original intention of the platform. "

Zhan, vice president of Phoenix Net-Peking University, is suspected of falsifying 25 papers. Is it "self-defeating" for overseas anti-counterfeiting websites to frequently shoot?
